  1. Ten Reasons to Buy a Network Camera or what your analog camera vendor won’t tell you

  2. Focus 10 of the most important functional differences between analogand network cameras

  3. 1 – End to interlace problems

  4. 1 – End to interlace problems • Interlaced scan • Each image formed from two interlace fields • Blurriness from capturing moving objects, even when connected to a DVR Progressive scan Crystal clearimages evenwith a highdegree of motionin the scene Entire imagecaptured atone time • Benefits • Superior image quality • Full image details • Precise, accurate information

  5. 1 – End to interlace problems En komplett bildruta med progressiv scan One complete frame using progressive scan

  6. Interlaced scan Progressive scan 1 – End to interlace problems

  7. 2 – Power over Ethernet increasessavings and reliability

  8. 2 – Power over Ethernet • Not available IEEE802.3af No need forpower outlet at cameralocation Industry standard • Benefits • Cost savings • Reliability with centralized power backup • Simple installation

  9. 2 – Power over Ethernet Both network cameras with andwithout built-in support for PoEcan take advantage of a UPS device

  10. 3 – Megapixel resolution

  11. 3 – Megapixel resolution • Stuck with NTSC/PAL resolution • 0.4 Megapixel at 4CIF and 0.1 at CIF • Limited image details Many resolutions Different aspect ratios 1 megapixel is 10x theresolution of CIF,2 megapixel is 20x! Digital PTZ • Benefits • More details, easy identification • Digital PTZ, higher reliability and simultaneous pan/tilt

  12. 3 – Megapixel resolution Megapixel CIF

  13. Aspect ratios 3 – Megapixel resolution Resolution comparisons

  14. 4 – Intelligence at the camera level

  15. 4 – Intelligence at the camera level • Not available Intelligent video Purpose-built, highlyintegrated hardware Intelligent features: Built-inVMD, Alarm management,Image enhancement Intelligent algorithms:Number plate recognition,People counting • Benefits • More details, easy identification • More productive and effective means of surveillance • Event-driven • Scalable systems

  16. 4 – Intelligence at the camera level Included Excluded Excluded Included Hallway Door

  17. 5 – Integrated PTZinput/output control

  18. 5 – Integrated PTZ input/output control • Cabling separate from the video signal • Costly and cumbersome PTZ control overthe same networkthat transportsthe video PTZ commandssent over theIP network Integrated I/O can trigger anything and be triggered by anything • Benefits • Less cabling, cost savings, increased functionality and integration potential

  19. 5 – Integrated PTZ input/output control Example: Typical I/O use –integration with alarm

  20. 6 – Integrated audio

  21. 6 – Integrated audio • Only possible with separate audio lines to the DVR Audio captured atthe camera Synchronized withthe video Two-way audio (duplex, half duplex, simplex) Can be integrated intothe same video stream • Benefits • Many possibilities: simplex, half duplex, full duplex • Synchronized audio and video • Easy to install, cost savings

  22. 6 – Integrated audio Example: Communicate andopen a door remotely • Entrance control • Remote dialog and gate/door control • Listen in on remote sounds • Audio surveillance • Provide audio feedback to surveillance scenes

  23. 7 – Secure communication

  24. 7 – Secure communication • No encryption • No authentication • Anyone can tap into the video or replace the signal from a camera with another video signal Video encryption Authentication usingencrypted certificates Privacy Authorization: to verify and approve the identity of the device • Benefits • Secure image capture • Secure transmission • Evidence trail secured

  25. 7 – Secure communication • Examples of achieving privacy • VPN • SSL/TLS (HTTPS)

  26. 8 – Flexible, cost-effective infrastructure choices

  27. 8 – Flexible, cost-effective infrastructure choices • Expensive coax, proprietary fiber, wireless • Distance affects image quality • Adding power, I/O and audio further complicates this situation IP = established,standardized,interoperable Digital images =no quality reduction A single network wire =hundreds of simultaneousfull frame rate video streams Many streamstransmittedover the same line • Benefits • Image quality, flexibility, scalability, future-proof • Resulting costs comparatively low

  28. 8 – Flexible, cost-effective infrastructure choices IP in security IP in BuildingManagement Systems TheIP way IT– Securityconvergence IP inIndustrialSolutions IP in VoiceOver IP

  29. 9 – True digital solution

  30. 9 – True digital solution • With every conversion image quality is lost: • Analog signal digitized in camera’s DSP • Digital signal converted back to analog for transport over coax • Signal once again digitized at the DVR for recording Images digitalized once Stay digital No image degradation No unnecessaryconversions • Benefits • Superior image quality

  31. 9 – True digital solution

  32. 10 – Lower total cost of ownership

  33. 10 – Lower total cost of ownership COMPARE • The cost per channel • Flexibility and performance CONSIDER • Back end applications and storage • Industry standard, open-system based servers vs. proprietary hardware like a DVR • Infrastructure used • Can it be leveraged for other applications?

  34. Conclusion The future belongs tonetwork cameras

  35. The future belongs to network cameras Market reports Remote accessibility Easy, future-proof integration Scalability and flexibility Cost-effectiveness Distributed intelligence Proven technology
